FERTILIZER-DISTRIBUTER.

srnorrrenrroiv 'forming part or Letters Patent No. 280,932, dates July 1o, ieee.

' Application tiled February 26, 1883. (No model.)

the novelty consists in the construction and arrangement of parts, as will .be more fully hereinafter set forth, and specifically pointed l out in the claim.

The object of the4 invention is to provide a device which will. grind, disintegrate, and distribute the fertilizing material as the wagon containing said materialpasses across the field, Aand to have thegrinding-power obtained from the saine power which impels the wagon; and to this end the invention consists in the construction fully illustrated in the accompanying drawings, which forni a part of this speciiication, and in which-' r Figure l isa side elevation, showing the device attached to a wagon and in operation;

Fig. 2, a cross-section; Fig. 3, a top plan view;

Fig. 4, a side elevation of the back; Fig. 5a bottom plan view, withl the device shown in Fig. 6 removed. Fig. 6 is a perspective view of the spout-frame; and Fig. 7 is a perspectiveview, showingthe :means for adjusting the device in relation to the wagon.

Referring to the drawings, A represents the wagon, of any ordinary make, having guides a to receive the arms b, which support thc device. 'Ihese arms I1 carry a frame, C, having `internally-projecting teeth or pins c, and which furnishes journal-bearingsfor a shaft or roller, D, having radially-projecting pins d. One or both of the rear wheels ofthe wagon A is provided with a sprocket-wheel, F, overwhich passes a chain, f, said chain' passing over a proper pulley or sprocket, D', and this ar- 45 rangement gives motion to the roller D.

To insure the proper tension to the chain, and to adjust the device properly in relation to the wagon, I form a long horizontal slot, b', in the arms b, and two slots, b2, vertically therein.

The frame C is supported upon a plate, B, which works linthe horizontal slot b, while pins In, rigid with the plate B, operate in the slots bf.. The plate B has a threaded portion, b5, upon which a thumb-nut, bi, operates to throw the plate backward or forward.

A concave-convex bottom, H, is provided with three or more apertures, h., governed by valves hf, 'one end of each of which is secured to the frame C and the other ends to a bar, `H, which may be manipulated by alev'er, I,

to adjust the size of the apertures h at will.

A frame, J, is provided with spouts j, corresponding with the apertures II., and the two 65 outer ones serve to throw the iertilizing Inaterial outward from the center.

Upon -the frame C rests a hopper, K, hav'- ing inclined partitions k, which tend to throw the material toward the different groups of 7o pins d upon the roll D.

vThe device, it will be observed, is secured to the rearof a wagon, and the material may readily be thrown from the wagon into the hopper.

The operation is obvious.

That I claim as new is- The plates B, having threaded portion Z, the frame C, and nutb, combined with the arms b, having slot b and slots b2, as and for 8c the purposes set forth.

In testimony whereof I afiix my signature, in presence of two witnesses, this 21st day of February, 1883.
